To all whom it may concern Be it known that l, Nonnis Emronn CLARK. a citizen of the United States residing at Plainville, in the county of l'lartitord Qcl. State of Connecticut, have invented certain new and useful Improvements in liecticu of which the following is a specification.

' This invention relates particularly to lathing, roofing, sheathing" and similar structures for affording support or reinforcement to Walls, roofs, floors, ceiling. etc, Where cement, plaster or concrete is used.

The mainobject is to provide a light but strong fabric which can be made and erected cheaply and which will receii e the plastic material properly and hold it securely. The proportions and design may be Varied considerably to suit different conditions of use. The form shown is adapted to be used without any centering: In its preferred form it consists of longitudinal members having lateral extensions connected by bridges Whose upper members are connected. The terms upper and lower, longitudinal and transverse are relative and not intended to limit the fabric to use in a horizontal, Vertical or inclined position.

Figure 1, is an end VlGW of a fragment of fabric embodying in" invention. Fig. 2. a *1 the same. Fig. 3., is a section of the fabric on the plane of the line X-X Fig. 5. l 'igr. l. is a perspective. rien' of a tragrnient of fabric. l iq'. is an end. View of fabric. the longitudina members of which are corrugated or folded.

' For convenience in reference the main longitudinal members 1 2 and 3 will be termed rods. Their crosssectional shape is in'nnaterial. Extending laterally from the side rod 1, are a series of cross bars such 4: and 5, Similar cross bars such as 6, 7, 8 and 9 project from the rods such as 2.

The pairs of strands 10, 11 and 12, 13 form arches which support the beam 14. The beams 14, 15, etc. are preferably connected by a longitudinal rod 16. The arches between the rods a re inclinen away from each other, the interior angle a being preierabhy somewhat less than 90. The inclined arches and the beams form rig-id bridge-like trusses which will support great Weights. The ends of the st ands preferably project downward so as to form feet 17 and 18 on which the Specification of Letters Zia-tent.

Ell .ZEGULATED METAL FABRIC.

.Ecrial lLr stretched or ended laterally so to form openings 19 30 The size of these openings will depend upon the pronortions of the members and the degree of lateral ex pansion. 1

ilhere greater strength is desired,the rods 21, may he made Wider and folded or corrugatedas shown in F 5. -This increases the stiffness and the lateral folding or bending of the rods brings the inclined members 24 and 25 nearer together thus diminishing the size of the o enin s. There is no need for any centering when this type of fabric is used for cement, concrete or plaster reinforcement. The corrugation may be sufficient to compensate for or negative the lateral expansion incident to the bending of the strands. In this case the product is of the same or less area than the original sheet.

The fabric illustrated is the same on both sides so that it reversible. This is also more uniform in strength than it would be if for instance the upper rod 16 were omitted from the structure of Fig. i. T he spaces 26 and 27 between the inclined members are an dcrcut or dove-tailed in section so that when the fabric is inbedded in cement or the like, the anchorage is very secure. Even in light L weight metal the fabric still enough to permit Walking upon it when erecting a floor or roof.

What I claim is:

1. An integral c-penworl; fabric comprising" rods in one'plane having laterally projecting bars. inclined arches projecting transversely therefrom and bars in another plane parallel to the plane of the first bars and connecting the upper ends of said arches, each arch con sting oft two strands parallel to each other.

2. An expanded metal fabric comprising reticulated sections forming plaster receiving surfaces in one plane, reticulated sections forming plaster receiving surfaces in another plane spaced apart from but parornied V allel to the first mentioned plane, the edges of the sections in one plane overlapping the prising parallel rods in one plane, bars in the same plane projecting perpendicularly from sa1d rods, bars in another plane parallel to the first mentioned bars and trans verse strands extending relatively at right angles to said rods and connecting the adjacent ends of bars in the two planes.

4. An integral openworltfabric comprising two series of rods lying in different but parallel planes, series of parallel bars projecting laterally from each rod and transversejstrands connecting the ends of the bars of adjacent rods and inclined so as to form clove-tailed shaped spaces between them.

5. An integral openwork fabric comprising a series of parallel rods, bars projecting laterally therefrom, parallel strands connected with said bars and extending at an angle thereto and having downwardly projecting feet and cross bars connecting the upper ends of opposite strands in a plane spaced apart from the plane of said rods.

6. An integral openwork fabric comprising two series of rods in parallel planes, a series of bars projecting laterally from each rod and forming in conjunction therewith two spaced plaster supporting surfaces, transverse parallel strands connecting the ends of said bars and oppositely projecting feet at the points of connection.

7. an integral openwork fabric ccinpris ing a series of parallel rods, a series of bars projecting laterally therefrom, inclined arches rising from adjacent )a rs and having their tops extending out of the plane of said rods and bars connecting the tops of the op posite arches in in plane spaced apart from the plane of said rods, each arch consisting of two parallel strands.

8. An integral openworlt fabric coinpris ing two series of rods lying in diiierent but parallel planes, a series of parallel bars projecting laterally from each rod and transverse strands-connecting the ends of the bars and inclined so as to form dove-tailed shaped spaces between them, some or" said rods heing corrugated.

9. An integral openwork fabric comprising a series of parallel corrugated rods, bars projecting laterally therefrom, inclined transverse strands connected to said bars andextcnding at an angle thereto and hav ing downwardly projecting feet and men1- bers connecting the upper ends of said strands in a plane spaced apart from the plane of said rods.

10. An integral openwork fabric comprisject-ing from the arches beyond each plane,

each arch consisting of two parallel strands.

11. A dovetail corrugated expanded metal element comprising three parallel ribs, the central rihilying in the base of the corrugation in a plane parallel to that of the two outer rib's,"said central rib being connected to the two outer ribs by zigzag bar members forming the sides and portions of the base of said corrugation.

12. An expanded metal sheet having a series of longitudinally extending dovetail corrugations formed therein, the base of each corrugation lying in a plane parallel to the general plane of the sheet, a rib formed in the center of the base of each corrugation, said rib beingconnected to parallel ribs in said sheet by zigzag bar mem bers forming the sides and portions of the base of said corrugation.

13. A dovetail corru ated reinforcineele' inent composed of an expanded metal sheet having a longitudinal rib formed in the center of the base of each corrugation, said ribs being integrally connected by zigzag bar members forming the sides and portions of the bases of said dovetail corrugations.
